OIL BURNER.

- side of the wick for a comparatively slight extent of its circiunference.

A difliculty qulte common in burners of this character and whichmust be avoided if the burner is to'operate satisfactorily is a tilting tendency and consequential binding of the wick between the tubes. Heretofore this difficulty has been overcome to a considerable degree by projecting Outwardly, as by fiuting Or paneling, a part of the inner wick tube in the vicinity of the wick raising mechanism to provide a guiding surface between which and said mechanism the wick is practically entirely supported, the remainder of the wick being substantially free from or out of material contact with the wick tubes so that friction or undue drag upon the wick is prevented. However to form the inner wick tube as stated complicates production and accordingly increases the expense of manufacture.

It is the aim of my invention to effectually eliminate binding and accomplish easy ac tion of the wick by simply assembling the inner and outer wick tubes in slightly eccentric relation, having them nearest each other on the side where the wick raising mechanism is situated. The wick, with its carrier, is of a diameter practically midway betweenthe diameters of the wick tubes so that it is out of frictional contact with the inner tube throughout all but a slight extent of its circumference where it is held against said tube by the wick raising mechanism that engages the outer side of the wick, and is free from material contact with the outer tube practically throughout its entire circumference. Thus the wick rides upon a comparatively narrow portion of the innor wick tube and has a bearing thereon equal to the longitudinal extent of the wick Specification of Lett'ersPatent, Patented Feb 7" Application filed May 4., 1920.

wherefore the wick is kept from w i to any appreciable degree.

In the drawing accompanying and form:

ing a part hereof,Fig. 1 is a plan view of a burner embodying my invention; F ig, 2

is a horizontal section on the line.2,-2 of Fig. 3; and Fig. 3 a central verticalsect'ion onthe line 3--3 of Fig. 1. v

The inner wick tube 11 terminates; atits lower end inan outwardly directedflange 2 whereonan inturned flange .3 of the outer wick tube l is superimposed, and the wicktubes are connected together in eccen trio relation to each other through theconnection of these flanges as by the soldering of them together so that a liquid tigl'it joint closes the bottom of the space between the tubes wherein a tubular wick 8, supported within a carrier 9, is adapted to be raised and lowered by means of a wick raising spindle 10 that has secured to its inner end pinions 11 that mesh with perforations 12 of the wick carrier 9. Following the usual. practice, the wick raising spindle 10 extends forwardly and upwardly through a tube 15 which joins at its inner end a'casing 16 that extends from the side of and opens through the outer wick tube 4 and encloses the inner end of the spindle and the pinions 11 that are'secured thereto. Byreason of the inclination of the spindle, the wick is given a spiral movement when it is raised and lowered, and the perforations 12 of the carrier 9 are arranged in rows that are inclined to the vertical axis of the wick corresponding to the inclination of the plane of the pinions, such arrangement being well known in the art.

The burner is mounted upon a supply pipe 20 fromwhich the wick space derives its Oil through the usual elbow connection 21, the burner being bound to the pipe by, means of a clamp 22 which surrounds the pipe and connection. At the opposite side, the" burner is held in proper relation to the pipe by means of a hook 23. p

It is obvious from the foregoing description that the wick bears on that longitudinal portion of the inner wick tube which is 013- posed to the pinions 11 so that throughout the remainder of its circumference the wick floats, so tospeak, in the space between the tubes. It may be mentioned in this connection that the portion of the outer wick tube in the region of the wick raising means or pinions 11 is depressed inwardly in opposed relation to the aforesaid longitudinal. portion of the inner wick tube thereby to assist in supporting the wick in the manner stated.

A further advantage of my improved construction over the fiuting or paneling of the inner wick tube is its freedom from vertical abutments (as produced by the edges of the flutes or panels) and whereon any slight irregularities or spurs on the wick carrier might be apt to catch and tend to restrict the wick to a directly vertical course in opposition to the spiral movement imparted to it by the wick raising spindle. Having thus described my invention, what I claim is:

1. In a burner of the character described, the combination of inner and outer wick tubes in eccentric relation to each other, a wick in the space between said tubes, and wick moving means operating on the outer side of the wick in opposed relation to that portion of the inner wick tube that is nearest the outer tube.

2. In a burner of the character described,

the combination of inner and outer wick tubes in eccentric relation to" each other a wick in the space: between said tubes, and wick moving means operating on the outer side of the wick in the zone of that portion of the inner wick tube that is nearest the outer tube, the part of the outertube in the region of said means being depressed in wardly in opposed relation to the aforesaid portion of the inner wick tube.

8. In a burner of the character described, the combination of inner andv outer wick tubes in eccentric relation to each other, a wick and its carrier disposed within the space between said tubes, at wick raising spindle carried by the outer tube the axis whereof is substantially tangent-to the tube and inclined with respect to the axis thereof,

and apinion on the spindle cooperating with the wick carrier to impart a spiral movement thereto when the spindle is turned.

In testimony whereof, I hereunto afiixmy signature.
